Improvement in ruling-pens



UNITED STATES WILLIAM O. HIOKOK, OF HARRISBURG, PENNSYLVANIA.

IMPROVEMENT IN RULlNG-PENS.

Specification forming part of Letters Patent No. 140,272, dated June 24,1873; application filed April 29, 1873.

To all whom it may concern:

Be it known that I, WILLIAM O. HIoKoK, of Harrisburg, in the county ofDauphin and in the State of Pennsylvania, have invented certain new anduseful Improvements in Ruling-Pens and I do hereby declare that thefollowing is a full, clear, and exactdescription thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, making a part of this specification.

The nature of my invention consists in the construction of metalruling-pens, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a plan view, and Fig. 2 a side View of my improvedruling-pen.

A Arepresent the upper parts, and B B the points of my ruling-pens. Theupper part A is made of heavier brass, and cut or struck up in onemachine, forming a base-plate with one or more fingers, while the pointB is made of thinner brass of the same thickness throughout, and made orstruck up on another machine, with an enlargement or socket formed atthe upper end to slip over the ends of the fingers of the part A, afterwhich the two parts are soldered together, so that at the top is a verystiff part,'and the lower part much thinner, making a fine point. As thelower part B is of uniform thickness the pen will be the same till usedup to the base.

The usual ruling-pens are made of heavy brass, with one end ground orcut down, and cannot at the point be of the uniform thickness all theway up, as the brass must be unequal all the way; while in my pen, itbeing made in two parts, the point is of the same thickness throughout.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-- T heWithin-described ruling-pen, consisting of thepart A, composed of theplate and the short fingers, made of one piece of thick metal, and thepoints B B, made of thin metal, provided with sockets at their innerends, which slip over and are soldered to the ends of the fingers of thepart A, all substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this11th day of April, 1873.
